Notes. The velocity range is that occupied by the full line profile and used in particular to calculate the line area. For undetected sources, the velocity range is the total analyzed range (centered on the velocity of the source deduced from optical data). The uncertainty of the area has been calculated considering the number of spectral channels included in the equivalent line width (given in the last column, see text). An asterisk indicates value assumed from data of other lines. Uncertain values are indicated by the symbol ~.
